By energizing the filaments 31 of the rectifier elements I3 from a suitable sourceor sources of filament energizing power, the laments may be constituted as electronemitting sources. Elec- 5 trons emitted by each filament travel to and impinge upon the corresponding anode'sleeve 4I and thereby `form ay conduction path between'the anode and cathode of `each rectifier unit.. This conduction path, however, ftisof; unidirectionall lo character and will permit the iiow ofl electrical current in one direction only between the anode ,.and cathode fof each' rectifier element I3.
